Abstract

The invention provides a fastening device with an alarm function. The fastening device includes a bolt, a first magnetic field generator and pressure sensors; the first magnetic field generator is mounted on a fixing base of an object to be fastened; the bolt is arranged in a magnetic field generated by the first magnetic field generator; the pressure sensors are located between the bolt and the object to be fastened; the bolt has first coils, an energy storage device and an alarm device; the first coils are electrically connected with the energy storage device; the pressure sensors are electrically connected to an input end of a processor; the alarm device is electrically connected to an output end of the processor; and the energy storage device supplies power to the processor, the pressure sensors and the alarm device. The first coils are used to charge the energy storage device. When a signal detected by the processor through the pressure sensors is less than a preset value, the alarm device is controlled to send an alarm signal. The fastening device has high automation degree, simple structure, reliable passiveness and high practicability, is low in production cost, can eliminate the safety hazard of production equipment, and can ensure the safety of the high-speed operation of the object to be fastened.

Description

technical field [0001] The invention relates to a mechanical part, in particular to a fastening device with an alarm function. Background technique [0002] As an important auxiliary machine of a coal-fired thermal power plant, the blower mostly adopts an axial-flow fan with adjustable blades, and its adjustment adopts hydraulic adjustment. When the axial-flow fan adjusts the blade angle, the actuator outside the fan drives the adjustment drive device. The hydraulic mechanism is activated by adjusting the fork, and the adjusting mechanism at the hub is pushed to rotate the angle of the blade. The rotating oil seal is the hub for adjusting the fork and the hydraulic mechanism, and is a dynamic and static component. During operation, the connecting bolts of the rotating oil seal are easy to loosen and fall off during frequent adjustment of the rotor blades, causing the rotor blade adjustment mechanism to disassemble, seriously affecting the normal operation of the unit, and ev...
